How are you all doing i just made this account! my name is chris by the way!

alright well my problem is i have a 1991 honda crx with a b16a in her.. now i converted it from obd0 to obd1, the ecu dizzy and all... Now when im driving my baby once i get to around 6500 rpm my vtec will kick in for a slight second "i could hear it" but after that it will stop and the rpm will not go any higher, before you all ask if i have any codes showin yes i do... im throwing out code #2 also #21..

2- o2 sensor but i dont know which one...

21- vtec selonide..

so im wonder if any of you honda pros could give me a little info on how to make my baby scream! lol..

well i guess i got about 4 more posts for the day seing as this is a new account!

Thanks for all the help!

The gasket for your VTEC selenoid has a screen in it, maybe check that and see if its clogged, and while its off clean the whole thing with carburetor cleaner. If that doesnt do it you may need a new selenoid. The O2 sensor code shouldnt have anything to do with this problem. But if you have no catylitic coverter or if its just a really old cat im sure its you secondary O2 that is failing. If you have no cat you can get O2 simulators to fix that problem.

 

what is a o2 simulator>? and what does it actually do?

 

also when im driving it seems like its kinda slow could that be because i have 17'' sinko's on her or because its in limp mode, also would throwing code 21 cause me to be in limp mode!

Thanks

tttt

BUMP!

 

alright well i did what you all told me to do i tolk it apart, and the screen didnt look clogged so i cleaned it out any ways! now my car is still showing code21 and i cant get my rpm past 6000 it will hit six and if i hold the gas the rpm will drop! now i need some help i have some PICS!!!


ok first off i need to know what the hell this is! its not connected to anything! and in a later pic ill show you some thing!



now this is where i think it should connect to but when it is connected my rpm will stay at a higher rpm like 3500 and sit there!



now here is a pick of where the vtec selonide conects to the head does it look ok?



and this is the ctec selonide! i dont have the gasket seal on it as my dad was cleaning it at the time!




ok come on guys work your magaic and let me know whats up!

thanks

???? As you accelerate, does your tach seem to bounce around ????

no not at all!

 

I thought you need a 4 -wire O2 for obd 1?

 

well i dont really care about the o2 sensor i will deal with that later! my main concern is why my vtec is not working!

 

have you checked to see if the VSS (vehical speed sensor) is hooked up.? if the speedometer does not work vtec will not work.

how do i check if its hooked up do you have any pics? also my speedo needle is past the 220km mark on it and it stays there how would i go buy fixing that?

i need to know what thoes are?

 

BUMP come on guys help me out!

 

ok, you're getting some good infor mation, and some bad information.
your car, being obd1, and assuming you have an obd1 p30 ecu, should only have one O2 sensor.
What I would do is grab the vtec solenoid off a friend's car and try it. I believe the D series ones will bolt up too. If that fixes it, you have a solution. If not, you wasted 20 minutes and a few drops of oil.
Now the thing on your intake manifold is what's called a throttle chaser. You don't need it. What it does, is when you let off the throttle, it's supposed to bump open the TB just a hair so it revs down smoother. If the link to the TB gets bent, it will make it idle higher. I wouldn't worry about hooking it up. Never have, never will unless it's already done.

Back to the vtec solenoid. I would run a continuity test from the solenoid to the ecu wiring. That will tell you if there is a break in the line. If so, run a new line or track down the break and fix it. If it's good, it's most likely the solenoid or low oil pressure.

alright thanks, but now i need to find some one with vtec selonide that i can borrow? but some one previosally said that if my spedo is not working then my vtec will not work! well in this pic shows you where my spedo is at.. it doesnt move it just stayes there..

 

BUMP!!!

 

if you speedo isnt working, check your VSS (vehicle speed sensor on the back of the trans) if this isnt solved, you def wont get VTEC to work...

 

you have a pic to show me exactly where it is sorry im kinda not used to this! i previousally had a 1986 crx carbed not fi? so there is a lot i need to learn!

 

tttt

 

bump

 

bumpty bump bump....

or at least send a link to where i could find it! like a online haynes manuel for b16a?
